AI calorie photo tracker
Protokl vs Cal AI
Cal AI nails one thing: photograph your plate and get a fast calorie and macro estimate. Protokl does that too — and then programs your training and forecasts your body composition, so logging actually connects to a plan.

What Cal AI does well
- Dead-simple, single-purpose experience built entirely around fast AI photo logging.
- Available on iOS and Android; Protokl is iOS-only today.
- Very quick to start if all you want is a calorie count from a picture.
Where Protokl is different
- All-in-one: AI meal-photo logging plus science-based strength programming and a body-composition forecast — not just calorie counting.
- A body-composition forecast projecting your weight, body fat %, and lean mass 3–12 months out from a thermodynamic model.
- Workouts that auto-progress with progressive overload from your performance, recovery, and goal weight (a deterministic algorithm, not generative AI).
- Macros that adapt weekly as your intake and weight change.
- Deep Apple Health integration across 50+ data types, kept on your device.
Pricing
